Magnesia backing mix (MIPEX)
A carefully formulated magnesia spinel packing, MIL-12, supplied as a dry powder around induction melting crucibles and transfer ladles.
Key benefits
Talk to a Technical ExpertGrips through the heating cycle
High thermal expansion holds the crucible firmly against the coil throughout the severe thermal heating cycle.
Forms a supporting spinel
On cooling MIPEX forms a spinel that keeps supporting the crucible body, for a longer working life.
Matched to the crucible
Formulated to work with magnesia, high alumina and chrome alumina crucibles and transfer ladles.
Simple dry powder packing
Supplied as a dry powder, MIPEX is packed quickly and consistently around the crucible in the coil.
